I am using weblogic integration platform 8.1 running jdk1.4.2_11. And we are facing OOM issues.
Hence I want an heap dump to analyse.
But the option -XX:-HeapDumpOnOutOfMemoryError does not work. Nor does HAT.
Tried to generate a heap with JMAP. But the heap dump does not open in HAT/MAT,IBM HA etc.

No monitors work due to lack of JMX. Kindly help as how I can get a proper heap dump.
